Specification of Letters Patent.

Patented Aug. 14,1906.

Application led December 2l, 1.905. Serial No. 292,844.

To all whom, it may concern:

Be it known that I, FRITZ WENDLER, a subject of the German Emperor, residing at Glatz, Silesia, Germany, have invented certain new and useful Improvements in Trace- Hooks andI do hereby declare the following to be a full, clear, and exact-descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in trace-hooks or fastenings wherein a swiveling slip-hook attached to the whiffietree or other part of a vehicle for securing the trace is locked in position by a link, and has for its object to prevent the locking ring or link, by means of which the hook is prevented from turning round, from slipping off the hook through violent jolting. For this purpose the locking-link is replaced by a fork or link supported not below, but above, the end of the slip-hook and acts as a gravity-pawl and receives the end of the hook between overhanging arms or sides. In consequencey of this arrangement this securing part has a constant tendency to adjust itself in the osition in which the hook is secured, so tfiat even in the case of sudden and vigorous olting the locking part can never be entirely moved out of the locking position and also always falls back into its first position.

In the drawings two forms ofthe invention are shown.

In the form of the invention illustrated in Figures 1 to 3, Fig. l is a side elevation of the trace-hook; Fig. 2, a plan of the same, and Fig. 3 a section throu h A B in Fig. 1. The locking part a is for -shaped, so that the arms b c of the fork drop down over the end of the hook. The part a is pivoted at e in such a manner that it has a constant tendency to fall into the locking position. The

back end of the bar f is preferably tapered at g, so that when the fork a is pressed down the arms b c bind' against the tapered part g, and

`thereby hold the parta in position.

`constant tendency to adjust itself in the locking position. In Figs. 1 and 4 the positions into which the locking parts must be brought in order to loosen the connection are indicated by dotted lines.

What I claim, and desire to secure by Letters Patent, is-

l. In a device of theclass descirbed for fastening traces, the combination with a swiveling slip-hook, of a gravity-catch adapted to secure the end of the hook against turning round.

2. In a device of the class described -for fastening traces, a fitting or support adapted to be fixed to the whifietree or other part of the vehicle, a slip-hook mounted to In testimony whereof I have a iXed my signature 1n presence of two witnesses.
